2017-06-28rsi: add in missing RSI_FSM_STATES into array fsm_stateColin Ian King
Two recent commits added new RSI_FSM_STATES (namely FSM_FW_NOT_LOADED and FSM_COMMON_DEV_PARAMS_SENT) and the corresponding table fsm_state was not updated to match. This can lead to an array overrun when accessing the latter two states in fsm_state. Fix this by adding in the missing states.

When user adds a virtual interface driver will set the bss_type to the iface_type given by the user. When supplicant is started on the same interface, a call to change_virtual_intf will be triggered if if_type is not NL80211_IFTYPE_STATION. Here driver should not update it's bss_type, because bss_type is intended to indicate the original iface_type and changing the same will defeat the purpose of creating this interface.

The bug was triggered when do suspend/resuming continuously on Dell XPS L322X/0PJHXN version 9333 (2013) with kernel 4.12.0-041200rc4-generic. But can't reproduce on DELL E5440 + AR9300 PCIE chips. The warning is caused by accessing invalid pointer sc->rng_task. sc->rng_task is not be cleared after kthread_stop(sc->rng_task) be called in ath9k_rng_stop(). Because the kthread is stopped before ath9k_rng_kthread() be scheduled. So set sc->rng_task to null after kthread_stop(sc->rng_task) to resolve this issue.

2017-06-28ath9k: fix tx99 use after freeMiaoqing Pan
One scenario that could lead to UAF is two threads writing simultaneously to the "tx99" debug file. One of them would set the "start" value to true and follow to ath9k_tx99_init(). Inside the function it would set the sc->tx99_state to true after allocating sc->tx99skb. Then, the other thread would execute write_file_tx99() and call ath9k_tx99_deinit(). sc->tx99_state would be freed. After that, the first thread would continue inside ath9k_tx99_init() and call r = ath9k_tx99_send(sc, sc->tx99_skb, &txctl); that would make use of the freed sc->tx99_skb memory.

2017-06-27Merge branch 'nfp-get_phys_port_name-for-representors-and-SR-IOV-reorder'David S. Miller
Jakub Kicinski says: ==================== nfp: get_phys_port_name for representors and SR-IOV reorder This series starts by making the error message if FW cannot be located easier to understand. Then I move some functions from PCI probe files into library code (nfpcore) where they belong, and remove one function which is never used. Next few patches equip representors with nfp_port structure and make their NDOs fully shared (not defined in apps), thanks to which we can easily determine which netdevs are NFP's by comparing the NDO pointers. 10th patch makes use of the shared NDOs and nfp_ports to deliver netdev-type independent .ndo_get_phys_port_name() implementation. Patches 11 and 12 reorder the nfp_app SR-IOV callbacks with enabling SR-IOV VFs. Unfortunately due to how PCI subsystem works we can't guarantee being able to disable SR-IOV at exit or that it will be disabled when we first probe... We must therefore make sure FW is able to deal with being loaded while SR-IOV is already on. Patch 13 fixes potential deadlock when enabling SR-IOV happens at the same time as port state refresh. Note that this can't happen at this point, since Flower doesn't refresh ports... but lockdep doesn't know about such details and we will have to deal with this sooner or later anyway. Last but not least a new Kconfig is added to make sure those who don't care about flower offloads have a way of not including the code in their kernels. Thanks to nfp_app separation this costs us a single ifdef and excluding flower files from the build. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2017-06-27nfp: reorder SR-IOV config and nfp_app SR-IOV callbacksJakub Kicinski
We previously assumed that app callback can be guaranteed to be executed before SR-IOV is actually enabled. Given that we can't guarantee that SR-IOV will be disabled during probe or that we will be able to disable it on remove, we should reorder the callbacks. We should also call the app's sriov_enable if SR-IOV was enabled during probe. Application FW must be able to disable VFs internally and not depend on them being removed at PCIe level.

2017-06-27nfp: add nfp_app cleanup callback and make flower use itJakub Kicinski
Add a cleanup callback for undoing what app init callback did. Make flower allocate its private structure on init and free it from the new callback. While at it remember to set the app pointer to NULL on the error path to avoid any races while probe path unwinds.

2017-06-27nfp: add helper for mapping runtime symbolsJakub Kicinski
Move most of the helper for mapping RTsyms from nfp_net_main.c to nfpcore. Use the new helper directly for mapping MAC statistics, since they don't need to include the PCIe interface ID in the symbol name.

2017-06-27nfp: move area mapping helper into nfpcoreJakub Kicinski
nfp_net_map_area() is a helper for mapping areas of NFP memory defined in nfp_net_main.c. Move it to nfpcore to allow reuse and rename accordingly. Create an additional helper - nfp_cpp_area_alloc_acquire() the opposite of already existing nfp_cpp_area_release_free().

2017-06-27nfp: explicitly check if application FW is loadedJakub Kicinski
We support application FW being either loaded automatically at boot from flash or (more commonly) by the driver from disk. If FW is not found on disk and nothing is preloaded users are faced with this unintuitive error: nfp 0000:04:00.0: nfp: Failed to find PF symbol _pf0_net_bar0 We can do better. Since we rely on symbol table being present - check early if it could be correctly read out of from the device and if not print a more informative message.
